Pimples, also known as acne, are a common skin condition that affects people of all ages. They are caused by a combination of factors, including excess oil production, clogged pores, and bacteria. Pimples can appear anywhere on the body, but they are most common on the face, chest, and back.
Papules are small, red bumps that form when the wall of a pore becomes inflamed. Pustules are similar to papules, but they have a white or yellow center filled with pus. Nodules are large, hard, and painful bumps that form deep under the skin. Cysts are the most severe type of pimple and can cause scarring.
Causes of Pimples
The exact cause of pimples is not fully understood, but they are believed to be caused by a combination of factors, including:
Excess oil production: The sebaceous glands produce oil to keep the skin hydrated. However, too much oil can clog pores and lead to pimples.
Clogged pores: Pores can become clogged with dead skin cells, oil, and dirt. This can create an environment where bacteria can grow and cause pimples.
Bacteria: The bacteria Propionibacterium acnes (P. acnes) is found on everyone’s skin. However, in people with acne, P. acnes bacteria can multiply and cause inflammation and infection.
Hormonal changes: Hormonal changes during puberty, menstruation, and pregnancy can increase oil production and lead to pimples.
Stress: Stress can trigger the release of hormones that can increase oil production and lead to pimples.
